Problems solved by technology

[0005] When the number of receiving ends of a multicast group is quite large (for example, greater than or equal to 10,000), when a multicast message is copied and then the next multicast message is copied, the next multicast message will be copied. The delay in sending the message after copying is too long. From the point of view of the multicast group receiving the multicast message, data discontinuity will occur, which will affect the IP multicast capability.

Embodiment 1

[0079] see image 3 As shown, taking n multicast groups and multicast group addresses as MGID0-MGIDn-1 as an example, the method for copying and processing multicast packets is described, including:

[0080] Step 1. Scheduling and obtaining a multicast message from multiple cached multicast messages

[0081] Receive multiple multicast packets and store them in the ingress first-in-first-out buffer according to the priority. The priority of the multicast packet can be used as the weight, and the weighted fair queue WFQ scheduling can be used to obtain the first multicast packet. Group address MGID0. Of course, weighted round robin WRR scheduling or round robin RR scheduling may also be used in another embodiment.

[0082] Step 2. Receive the scheduled multicast message

[0083] Receive the first multicast message, you can know the target multicast group through its multicast group address MGID0, and further know the number of receivers included in the target multicast group,...

Embodiment 2

[0139] see Figure 6 As shown, a device for copying and processing multicast messages corresponding to the method for copying and processing multicast messages in Embodiment 1 still takes n multicast groups and the addresses of the multicast groups are MGID0-MGIDn-1 as an example.

[0140] A device for copying and processing multicast messages, including:

[0141] Copy confirmation unit 10: used to receive multicast messages, confirm the number of times required for all multicast messages to be copied according to the multicast group address of the multicast message, and obtain the preset multicast message copy processing times;

[0142] Replication processing unit 20: used for performing the preset multicast message processing on the multicast message when the number of times required for all copying of the multicast message is greater than the preset number of multicast message copy processing times Copying the number of copies processed, sending the copied multicast messag...

Abstract

The embodiment of the invention provides a replication and processing method for multicast message and a device thereof; wherein, the replication and processing method for multicast message comprises: receiving multicast message, determining number of times needed by the whole multicast message to be replicated according to the multicast address of the multicast message and obtaining the number of times of the replication and processing of the predetermined multicast message; when the number of times needed by the whole multicast message to be replicated is larger than the number of times of the replication and processing of the predetermined multicast message, the replication of the number of times of the replication and processing of the predetermined multicast message is carried out on the multicast message and the multicast message is stored. When the number of receiving ends of a multicast group is quite a lot and great amount of replications are needed, a user can preset the number of times of the replication and processing of the multicast message, thus reducing the replication delay of the multicast message.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for copying and processing multicast messages. Background technique [0002] The use of IP multicast technology (Multicast) can significantly reduce the bandwidth requirements of the network, reduce the network load, and improve the transmission efficiency of the network. IP multicast applications can be roughly divided into three categories: point-to-multipoint, multipoint-to-point, and multipoint-to-multipoint. Point-to-multipoint applications refer to one sender corresponding to multiple receivers, such as: Internet TV; multipoint-to-point applications refer to multiple senders corresponding to one receiver, such as online auction; multipoint-to-multipoint applications refer to multiple One sender corresponds to multiple receivers, such as a web conference. [0003] Specifically, in the IP multicast technology, the sending end sends multiple multica...
